Reviewed by Fujii Hironori.

C++20 introduces the std::remove_cvref type alias which can be used in place of
combinations of std::remove_reference and std::remove_const or std::remove_cv.

Older versions of GCC's standard library are covered by an already-existing
fallback. WTF::RemoveCVAndReference is basically the same thing and can be
replaced completely.
